Question

Which of the following summarizes photosynthesis?

A. glucose + carbon dioxide → oxygen + water
B. carbon dioxide + water → glucose + oxygen + water
C. oxygen + water → glucose + carbon dioxide + water
D. carbon dioxide + oxygen → glucose + oxygen + water

Answer 1

The answer is B because that is how plants give off oxygen.

Answer 2

Answer : The correct option is, (B)
`\text{carbon dioxide}+\text{water}\rightarrow \text{glucose}+\text{oxygen}+\text{water}`

Explanation :

Photosynthesis : It is a type of process which takes place in the plant cell. In this process the light energy converted into chemical energy.

As we know that the plant needs carbon dioxide, water and light. During the photosynthesis the carbon dioxide, water and sunlight react to gives glucose, oxygen and water as a product.

The balanced reaction will be,

`6CO_2+12H_2O\overset{sunlight}\rightarrow C_6H_(12)O_6+6O_2+6H_2O`

Hence, the correct option is, (B)
`\text{carbon dioxide}+\text{water}\rightarrow \text{glucose}+\text{oxygen}+\text{water}`
